Rapid7 have started an open-beta of AttackerKB, a community to discuss, analyze, and prioritize security vulnerabilities.
I've posted the blog about it instead of the direct link as I think it provides some valuable context.
The direct link for the site is here: https://attackerkb.com/
I thought this was something that the community here would be interested in as I see a lot of insightful comments regarding the latest hyped security vulnerabilities, take the other days comments on thunderspy as an example.
